The rising numbers and intensity of western disturbances (WDs) in pre-monsoon months are causing excessive but short rainfall spells across the country particularly in the Himalayan states. These events are then resulting in sudden flash floods and taking a huge toll on human life and public infrastructure. However, the specific monitoring and warning services for such disasters by the Central Water Commission (CWC) & Indian Meteorological Department (IMD) are largely unavailable as these agencies are mainly forecasting floods during the monsoon.

DRP NB 300924: Focus on River Studies
Rivers are the most important ecosystems (eco here includes ecology and economy) and yet possibly least studied entities. Some news below this week about some river studies brings the focus on need to take up many more river related studies.
Most important aspect of river related studies is the need for credible, independent studies, not influenced by the needs of the governments. Otherwise, the government is likely to not only influence the study, but also decide not to make it public as they did in case of the studies related to Joshimath town and role of Chamoli disaster.

DRP NB 160924: Urban Flood lessons from Vadodara, Vijaywada

Like every monsoon, a number of cities have faced catastrophic floods in SW monsoon this year. Vadodara and Vijaywada have got the media attention more than any other city for urban floods this year. In both cases a number of factors are common: role of upstream dams, encroachment on water bodies including rivers, lakes, streams, role of illegal sand mining particularly in Vijaywada, not having learnt any lessons from past flood disasters.
It is interesting to see Andhra Pradesh CM hinting at bringing HYDRAA like enforcement institution to remove encroachments on Budameru and other water bodies. Considering the nature of his politics and track record, it is doubtful if this NDA CM will take such a bold step, but it is certainly worthy of consideration for almost all urban areas in India.

DRP NB 260824: Urban flooding plan welcome, Urban Water Sector needs attention
(Feature Image: Assam Floods: Commuters wade through a flooded road after incessant rains, in Guwahati, Friday, July 5, 2024. Image Source: PTI/ABP Live)
The Union Government plan to spend Rs 2517 Cr in 2 years in seven metro cities to mitigate floods is certainly welcome announcement. The key component of the plan, conservation and improving capacity of urban water bodies is noteworthy along with storm water drainage. Does it mean that the River Front Development projects that actually reduce the flood carrying capacity of the rivers will be closed, since one does not expect govt to be working at cross purposes in different schemes.
In fact, Urban Water Sector as a whole needs attention with National Urban Water Policy as a first step. This is because the groundwater aquifers that are fast being emptied out, can be least cost option for storing the excess rain water, serving the purpose of reducing storm water drainage load and also improving water conservation. There is huge scope for this in all the seven metros listed in the scheme as also in many other cities.

Himachal Pradesh: 12 More HEPs Impacted by Cloudburst Disaster in July 2024
(Feature Image: Flashflood damaged Malana I HEP dam site & Sechi HEP powerhouse in Beas & Satluj basin. Image source: Social Media.)
The multiple cloudburst incidents between July 29 and August 01, 2024, has caused large scale devastation in Kullu and Shimla districts of Himachal Pradesh. The initial media reports in brief have mentioned that two hydro electric-power (HEP) projects namely 85 Mw Malana-I and 14 Mw GreeenKo Project being damaged by the flashfloods. The follow up reports have extensive coverage on rescue and relief works, but not much is revealed about scale of damages to the HEP projects.

DRP NB 120824: Chalakudy community demand Prudent Dam Management Plan

One of the heartening development this week is from Kerala, where Chalakudy river community held a satyagraha to demand proper integrated dam management plan in the Chalakudy River basin to minimize flood risks. It is rather rare that communities come out for such a demand. It was also great to see that the satyagraha was supported by Chalakudy Puzha Samrakshan Samiti, Chalakudy municipal chairman and also environmentalists.
The satyagraha in fact had specific demand for each of the dams included in the Paramibikulam Aliyar Project, including in Kerala and upstream Tamil Nadu. We hope the Kerala government positively responds to these demands at the earliest.

The cloudburst induced flashflood destruction took place late on July 25, 2024 in Palchan area of Manali tehsil in Kullu district. Many of the media reports have also mentioned about the deluge damaging a hydroelectric power (HEP) project in Palchan just in a single line without revealing any details or even the name of the HEP.
While looking for more information about the affected HEP, we came to know that not just one but two HEPs have faced significant damages due to the flashflood incident. Both projects are owned and run by private companies in upper Beas River basin.

DRP NB 220724: Why are Under construction hydro and dam projects excluded from dam safety regime?

As we saw in stories in last week (e.g., Luhri HEP in Himachal Pradesh) and see this week (Vishnugad Pipalkoti in Uttarakhand and Dibang HEP in Arunachal Pradesh), a number of under construction projects regularly face disaster, which includes deaths and destruction on large scale. We have been narrating stories related to disaster at such projects regularly in the past too.

DRP NB 080724: Why IMD & CWC are unable to improve forecasts, reporting & help improve flood management?
(Feature Image: Flood-affected people move to a safer place on a boat in Nalbari district on Friday, July 5, 2024. Image Credit: PTI/Source HT)
We are in the thick of monsoon and also flood season. To manage floods, key inputs are accurate forecasts and prompt, accurate, location, river specific rainfall. India Meteorological department has a key role to play in all these aspects that can help us manage floods, as a very pointed Editorial in Indian Express stated in the context of Assam Chief Minister Himanta Biswa Sarma’s flip flops.
The edit referred to the 2021 parliamentary panel report that asked the Centre to set up modern weather stations in the upstream catchment of the Northeast’s rivers and install sirens to alert people downstream of floods. North East and rest of the country continues to lack such systems.

DRP NB 010724: Time for independent review of Polavaram Project?
(Feature Image: Work going on Polavaram Project at Polavaram in West Godavari. DC Image: Narayana Rao, Dec. 2020)
The sequence of events over the last two decades that ended this week with white paper on Polavaram project being released by the newly elected Andhra Pradesh govt underlines urgent need for an independent assessment of the multi-state Polavaram Project on Godavari River in Andhra Pradesh.
The story of the project similar to, though a bit longer than that of the ill-fated Kaleshwaram Project of the neighbor Telugu speaking state of Telangana. Both are ill-conceived, expensive, high impact projects on same Godavari River, both taken forward without sufficient studies and implemented without sufficient checks and balances.
